I have 2 table top DAB radios that run on batteries:

(Bought them both from Sainsburys. They seem to be quite regularly
discounted to £40ish. I prefer the sound/build/use of the Sony)

I think they both advise against rechargeable batteries in the
instructions, but they both run fine. About 2 months I'd guess, used
maybe 20 minutes each day, using Aldi rechargeable C batteries.

Probably a stupid question, but I see that the Panasonic one's
description says "Whip aerial (FM)".
Does this mean that it/they have some sort of internal aerial for DAB?

No it means the whip aerial is long enough for FM. DAB is at a somewhat
higher VHF band III ~ 200MHz so about half the FM whip length is needed.

SHMBO has an awful Pure DAB radio in the kitchen and has to extend and
adjust the telescopic aerial constantly to hear any music amongst the
squawking choppiness of the output.

That is normal for DAB. You can make a dedicated aerial for it from some
coax (simplest type) or a dipole loop which will improve things a bit
but it still dissolves into boiling mud when it rains.

In the spirit of DIY. This describes the simplest method that works OK

Still only as good as the broadcast bitrate though
